RV Lead Pacing Percentage increased from 26.6% to 96.9%. Is this normal?

Hello Everyone,

I had a pacemaker implanted about 4 weeks ago. I am new to pacemaker and still getting used it to.

Today, I had a pacing test and the report shows RV Lead Pacing Percentage 96.6% which was 26.6% 6 days ago. 
Is this normal?

Wishing everyone a Happy and Healthy New Year.

Yes it can be normal

Hello HRB, Yes a sudden increase in pacing percentages can be normal depending on our heart condition being treated or whether the heart condition has changed?  Pacing percentages can also change if we are on any medication that will be slowing our heart rate for example, or whether there have been any dosage changes?  Most importantly, pacing percentages can change if there have been any pacemaker setting changes?  I am paced 100% in my right atrium, with only around 4% in the right ventricle.

If we need right ventricle support, then we need it.  I always go by how I feel.  If I feel well then I am happy to assume the level of pacing is about right for me.  If I feel unwell, then that is another matter and I would discuss any symptoms with my doctors.

Are you able to tell us why you needed a pacemaker?  That would help us to answer your questions more completely.

I wish you too a very happy and healthy New Year and I hope you will do very well with your pacemaker.

PM changes.

If they made any changes from one check to another, the percent will change. Setting changes will either pace you more or less to relieve symptoms. Unless your settings were never changed from one check to another than that mean a your condition worsened and you need more help with pacing. As my block got worse they needed to adjust settings and therefore I paced more and more.

Most of us with heart block pace ventricles every beat. 

There is no one number that's considered good or bad, whatever it takes to make us feel good is the right amount for us. Every time they adjust the settings, expect the numbers to change.

I have had dual pacemaker for 1 year after emergency surgery for a complete heart block.  Initially I paced roughly the same in both chambers.  Now suddenly I am pacing 59% in the  atrium and 2% in the ventricle.  Can anyone explain why? Thanks
